Two-loop scattering amplitude for heavy-quark pair production through light-quark annihilation in QCD
Abstract We present the first full analytic evaluation of the scattering amplitude for the process qq → Q Q ¯ $$ Q\overline{Q} $$ up-to two loops in Quantum Chromodynamics, for a massless (q) and a massive (Q) quark flavour. The interference terms of the one- and two-loop amplitudes with the Born am...
